身管内膛镀铬是减缓和防止内膛烧蚀、提高火炮寿命的有效方法之一。对此美国进行了长期大量的研究工作。实验已经证明,枪炮内膛镀铬后,寿命可提高两到五倍,镀铬工艺又比较简单经济,因此长期以来镀铬始终作为一种防烧蚀的方法在国内外广泛应用于小口径武器中,并正在进行大口径火炮镀铬的深入研究。在105mm、155mm、120mm火炮上已进行了射击试验,寿命都有提高。
Tube bore chrome is to slow down and prevent the bore ablation, improve the life of the artillery one of the effective methods. The United States conducted a large amount of long-term research work. Experiments have proved that after the chrome-plated gun bore, the life expectancy can be increased by two to five times. The chrome plating process is relatively simple and economical. Therefore, chrome plating has long been widely used in small-caliber weapons at home and abroad as a anti-ablation method, And is in-depth study of large-caliber artillery chrome plating. In 105mm, 155mm, 120mm artillery on the shooting test has been carried out, have improved life expectancy.
